I have a Nordic Track Audio Strider 900 and I have had it for a year. There is now a very loud intermittent sound coming from the back of the machine. It happens rather randomly- but when it comes, the sound is in sync with the movement of the pedals. Sounds a bit clunky- not squeaky. Any ideas?

Try spraying silicone spray under the belt. It worked on mine. You can buy spray cans from a Hardware or Bunnings etc.

Our Nordic Track machine intermittently runs its own diagnostic when you turn the machine on after it has been powered off. This includes the first time you take it out of the box. If you notice that the display screen is on but none of the function buttons work, listen for a humming sound at the base of the machine where the motor is housed. A tell-tail sign is that the motor that slopes the running track is raising or lowering the slope (as part of its diagnostic check) which is difficult to recognize when the track is not running. After perhaps one or two minutes, the button functions return and the machine "comes alive". If not, then you'll want to locate the Nordic Track service number and talk to a technician or representative.

Better to buy a new console. It would be difficult to repair the existing console.

Maybe there is a problem with either roller.
Do you think ?

Check all bolts .Ellipticals are touchy machines.
